The international agricultural product system is globalized and interconnected, and the trade plays an increasingly important role in facilitating agricultural product availability. In order to explore the geographical dynamic of international agricultural trade, a social network approach is implemented to examine the issue including countries’ centrality, international connectivity, and community in the network during 2005-2016. The results show that the agricultural product trade network is emerging increasingly complexity with disparity, hierarchy and modularity in the Belt and Road region. Most countries in the network have a great number of trade linkages, while larger trade volumes are still concentrated on fewer regional agri-product powers such as China, India, and Indonesia. International agri-trade linkages with high-value connectivity are obviously observed among some neighboring countries, especially between China and South Asia or Southeast Asia, and between Russia and Eastern Europe as well. The network has an obvious core-periphery structure, and its hub is composited of several Asia countries such as China, India, Indonesia and Malaysia, etc. Additionally, the heterogeneous structure has slightly been weakened over the period because of increment of sub-core countries. On the basis of block-modeling analysis, the agri-trade network can be classified into four modularities with geographical clustering property to a certain extent, which are named as the bidirectional spillover community, the agent community, the main spillover community, and the main beneficial community, respectively.
